Weird alien/monster pet/toy store in galleria mall?

This is a long shot, but sometime during the early/mid 2000s I have memories of going to the Galleria and walking past a toy shop that’s premise was “adopting” some sort of round alien/monster thing. I cannot remember anything about this store except that the lighting was mostly purple leds and they had tubes on the walls for the alien things. Does anyone remember a store like this and what it was called? I’m probably misremembering details but literally anything helps since it’s driving me crazy trying to remember
